As far as I remember, there isn't any version of firefly jumbo which has been recompiled with support for ucgo and ummu. If there was, I would be very happy.
There is just a firefly jumbo add-on for orbiter 2006, which has all the features you mentioned like shuttles and skids, etc. Thankfully, it is fully compatible with Orbiter 2010, but only partially compatible with 2016. The landing points are not compatible with Orbiter 2016
Hi Abloheet ,yes the final version of the Firefly,firefly shuttles,mule,and skids were UMMU,and UCGO,but they were lost when the Ragtag website shut down,I had them on my old HD that took a crap 3,or 4 years ago,but thanks for the reply,I assume somebody still has a copy here?
